Species found in Southern Mexico, throughout Central America and the West Indies to northern Brazil, Bolivia, and Peru. The tree's best development is on ridges or slopes and high riverbanks. The wood is used for furniture and tools. The tree exudes a resinous gum used in varnishes and scents.

Thought to be the ancestor of living Hymenaea species. Copal deposited from these extinct trees is highly valued for varnish. It had an extensive range, from southern Mexico and northern South America to the African continent. Studies of morphology and DNA indicate that H. protera was more closely related to the only species of Hymenaea remaining in East Africa than it is to the numerous American species.

Species of tree native to the east coast of Africa. Produces a resinous copal. Some authors place this African species in a separate monotypic genus, Trachylobium.

Members of an order of insects containing sawflies, wasps, bees, and ants.

Shape comprising the open surface generated by revolving a hyperbola about either of its axes. If the tranverse axis of the surface lies along the x axis and its centre lies at the origin and if a, b, and c are the principal semi-axes, then the general equation of the surface is expressed as x2/a2 ± y2/b2 − z2/c2 = 1.

Order of eel-shaped, scaleless, soft-skinned aquatic primitive vertebrates with paired thick barbels on the end of the snout, a tail fin (but no paired fins), no jaws, cartilaginous skeletons, mouths comprising round or slit-like sucking openings with horny teeth, poorly developed eyes buried under the skin, a single nostril at the end of the snout, and five to 15 pairs of gills used for respiration. They are found in cold seawater, habitually lie buried except for the tip of the head on soft bottoms and in burrows.

Creation of images by hyperspectral remote sensors which collect data simultaneously in dozens or hundreds of narrow, adjacent spectral bands. The images thus created are more detailed than those of other multispectral sensors with just a few relatively broad wavelength bands.

Úsese para designar elementos de conexión con la parte central y la periferia de un edificio de cinco partes estilo palladiano.

Disc-shaped objects made from papyrus, stuccoed linen, bronze, gold, wood, clay or resin, placed by ancient Egyptians under the heads of the dead. The disc, which was inscribed with images, symbolized the eye of Ra or Horus, and was related to the idea of resurrection.

Nicknames indicating a diminutive or affectionate reference. In English, often made with the addition of a "y" or "ie." An example would be "Annie" used for "Ann."

The condition of low oxygen; it is typically defined as a level below 20.9% in an atmospheric environment and in the range between 1%-30% saturation in an aquatic environment. Hypoxic conditions are detrimental to living organisms. In a conservation context, hypoxia may be deliberately induced as a means of preservation of materials or pest control. For the extreme condition in which oxygen is below 0.1% or absent, use "anoxia." For a medical condition characterized by low blood oxygen, use "anoxemia," for which "hypoxemia" is a used for term.

Physical features located on land, particularly those above sea level; either natural or man-made.

Field of study surrounding the earth's topologic features above sea level, especially the measurement and mapping of land features.

The measurement of altitudes; the distance of a part of the earth's surface in reference to height above or below the level of the sea.

Members of the order containing six species in one family. Living members are primitive hoofed herbivorous mammals of the family Procaviidae, the only surviving members of the order Hyracoidea, being small thickset, herbivorous quadrupeds, about the size of a large domestic rabbit, similar to guinea pigs in appearance, with tusk-like incisor teeth, and native Africa and the Middle East.

Genus of small dog-sized animals representing the oldest known horse; they lived in the Eocene Epoch. Characterized by a relatively short face, eye sockets nearer the middle than modern horses, and a short space between the front teeth and the cheek teeth (diastema).

A phenomenon by which the effects in a property lag behind the changes in the forces acting upon it such as magnetizing force or stress.

Nationality and culture of Kiribati, an island nation located in the central tropical Pacific Ocean.
